次に、本発明に係る使い捨て吸収性物品としての使い捨ておむつ10の実施形態について、図面を参照しながら説明する。なお、本発明に係る使い捨て吸収性物品は、使い捨ておむつに限定されず、下着又はおむつに装着される吸収パッドを含むものである。また、以下の図面の記載において、同一または類似の部分には、同一または類似の符号を付している。ただし、図面は模式的なものであり、各寸法の比率などは現実のものとは異なることに留意すべきである。したがって、具体的な寸法などは以下の説明を参酌して判断すべきである。また、図面相互間においても互いの寸法の関係や比率が異なる部分が含まれ得る。
図1は、本実施形態に係る使い捨ておむつ10の展開平面図である。図1に示す展開平面図は、使い捨ておむつを構成する表面シート50、サイドシート70等の皺が形成されない状態まで、立体ギャザーの伸縮部分を伸長させた伸長状態の図である。図2は、図1に示すA−A線に沿った断面図である。
次いで、防漏シート55について説明する。図3は、防漏シートを模式的に示した断面図である。防漏シート55は、吸収要素40よりも厚み方向Tの外側である非肌対向面側T2に配置されている。なお、防漏シート55は、吸収要素40よりも肌対向面側T1に配置されていてもよいし、吸収要素40よりも幅方向Wの外側に配置されていてもよい。
上述の実施形態の防漏シートは、保護層を有しているが、本発明に係る防漏シートは、保護層を有していなくてもよい。保護層を有しない防漏シートにおいては、撥水領域の少なくとも一部は、撥水層を厚み方向において三等分し、厚み方向の中央に位置する中央区域に配置されることが好ましい。
